To gurantee such a long insulator are straight , we huge up insulator on bottom during porcelain firing .
in this way , the insulator core will be not curved . althought it will increase production cost .
but final product qualified rate will be much higher , and final product will have excellent mechanical strength
and beautiful finish .
compare with silicone rubber line post insulators , porcelain line post insulators can work much longer time in lines. and it is free of maintanance .
We produce HIVOLT line post insulators with high quality materials :
1 the cap are made of high density ductile iron or malleable iron ,every pieces test qualified .
Both cap and assembly bolt are hot galvanized , zinc thickness meet related IEC and ASTM standard requirement
2 Porcelain the insulation part are made of high aluminum porcelain C130 . the porcelain surface covered a layer of hard and shinning glaze , color can be grey or brown.
3 We use Portland cement assembled insulator , which have very good mechanical performance and the quality more reliable .
Applications:
Suitable for transmission or distribution lines up to 69KV . The insulators are used as vertical position in lines, the insulator top are porcelain tie top , which can hold and support different size of conductors .
Competitive Advantage:
We use high aluminum porcelain , in this case , the insulator core diameter are smaller ,while the mechanical strength are in high level . compare with other supplier’s product , we decrease much the unit weight . it is more suitable for insulator assembly in lines , and make easier maintenance.
we offer 3 years up to 5 years quality guarantee . high quality deserve your trust !
The porcelain glaze are smooth and shinning , have a very good self-cleaning performance . it is easy for maintenance .
We can design insulators based on customer’s requirement or special technical specifications.
